Answer:
294 square units
Step-by-step explanation:
35^2-21^2=a^2
a^2=784
square root 784=28
21*28/2=294
Answer=294
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
Answer:
perpendicular
Step-by-step explanation:
because m1×m2=-1
Answer:

Step-by-step explanation:
Since emails arrive at a constant rate of 22 per day, the equation for n-th term can be modeled by a linear relationship of general form:

In this case, E₀ is the initial number of emails unread, 8, k is the rate at which emails arrive, 22 per day, and t is the number of days passed.
At t=n, the number of unread emails is:

The answer is 0.1250 I took the test and this showed up as the right answer. :)
